VULCANIZER.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed August 11, 1916. Serial No. 114,370.

T 0 all whom it may concern: 7

Be it known that 1, CHARLES LOUIS COOPER, a citizen of the United States, residing at Moran, in the county of Allen, State of Kansas, have invented a new and useful Vulcanizer, of which the following is a spec ification.

My invention relates to a vulcanizer for the repairing of pneumatic tires, especially automobile tires, in which only one form is used for all repairs to casings and inner tubes, and having a heater directly attached.

The objects of my invention are: first, to combine the necessary forms, namely, an inside casing form, an outside casing form and a tube surface, for the repairing of pneu' matic casings and inner tubes into one body, and the heating of same by a heater directly attached; second, to provide a cheap and simple means of repairing tires; third, to reduce the number of parts and make it compact and portable, so it can be carried along in an automobile and repairing done at any time or place; fourth, to produce a complete vulcanizer that can be sold at a low price.

The invention consists in the construction and novel combination of parts hereinafter fully described and illustrated in the accompanying drawing in which Figure 1 shows a side view, and Fig. 2 a face View of the vulcanizer; Figs. 3 and 4, a faceand end view respectively of the tube plate; Fig. 5, a side view of the yoke, tension hooks and chain; and Fig. 6, a side view of the tension bar and tension screws.

Similar letters refer to' similar parts throughout the different views.

The hollow metal form A., constituting the body of the vulcanizer, has at its lower end an opening below which a suitable heater D, is attached, the one shown in the drawing forming no part of my present in vention. This heater D, which heats the form A is attached by the screws C C, and regulated by the thumb wheel E. At the upper end of the form A is an opening B, to give draft to the heater, and into this opening a deflector N is placed to deflect any surplus heat out of the casing, when the vulcanizer is used inside of a casing, and away from the handle when the vulcanizer is hanging up. The dotted lines show the position of the deflector when the vulcanizer is hanging up.

An adjustable wood handle L, having a hook in the end, provides a means of handling the form when hot and for hanging up the device.

The lug M which is integral with the form A has an opening into which a thermometer, for registering the temperature of the form A, may be placed.

When repairing inner tubes, the tube is clamped between the concave surface F., of the form, and the tube plate Figs. 3 and 4:, which has a convex surface G that conforms to the surface F of the form. The yoke J, Fig. 5, containing the tension. hooks, I I, which fits onto the form A, being placed on the form at the center and secured by the setscrews K. K, the hooks I. 1. receiving the arms H. H. of the tube plate. Tightening of the winged nuts on the hooks I. 1. applies the necessary pressure to the repair. The concave surface F. of the form A, which conforms to the outside of a casing, is also used when making repairs to the tread and sides of a casing, and repairs are made while the tire is inflated. The yoke J. Fig. 5, containing the tension hooks I. I. is placed on the form, as for repairing tubes, and the chain, Fig. 5, passes around the tire and rim, from hook to hook. Tightening of the winged nuts on the hooks I. I. produces the desired pressure.

When repairing casing blow outs the form A, which conforms to the inside of a casing, is placed inside of the casing and the tension bar containing the tension screws, Fig. 6, is placed parallel with the face of the form, the ends of the tension screws bearing against the face of the form. A wrapping of tape, which passes around the tire and over the tension bar extends the length of the form. Tightening of the tension screws produces the necessary pres-- sure to the repair.

I am aware that prior to my invention vulcanizers have been made, having two or more separate forms, for making the dilferent repairs to casings and tubes, and I do not claim the method; but, I claim:

The combination in a vulcanizer of an inside form and an outside form and a tube surface, in one body, and having the heater attached direct.
